GHRP-2 Peptide
Ghrelin-mimetic GH secretagogue with appetite effects.
What is GHRP-2?
GHRP-2 is a growth hormone axis peptide studied for gh release in adult gh deficiency and appetite stimulation in cachexia models. Below is an educational overview of GHRP-2 peptide benefits, mechanism, common research protocols, dosage references, and known side effects.
GHRP-2 Mechanism of Action
A synthetic hexapeptide that activates the ghrelin/GHS-R1a receptor, stimulating endogenous GH release. Compared to Ipamorelin, GHRP-2 produces a stronger GH pulse but also modestly elevates cortisol, prolactin, and appetite.
GHRP-2 Research Areas & Benefits
GHRP-2 Dosage & Common Research Protocols
Combined with CJC-1295 or Sermorelin in research to amplify GH pulse amplitude.
Protocols summarized for educational reference from published research. Not dosing guidance.
GHRP-2 Studies & Cited Research
